library(registry): Manipulating the Windows registry |
The library(registry)
is only available on the
MS-Windows version of SWI-Prolog. It loads the foreign extension plregtry.dll
,
providing the predicates described below. This library only makes the
most common operations on the registry available through the Prolog
user. The underlying DLL provides a more complete coverage of the
Windows registry API. Please consult the sources in
pl/src/win32/foreign/plregtry.c
for further details.
In all these predicates, Path refers to a‘/’separated
path into the registry. This is not an atom containing‘/’-characters
as used for filenames, but a term using the functor
.
Windows defines the following roots for the registry:
/
/2classes_root
,
current_user
,
local_machine
and
users
.
prolog.type
.
Name is the name visible in the Windows file-type browser.
Finally, OpenAction defines the action to execute when a file
with this extension is opened in the Windows explorer.shell_register_prolog(Ext) :- current_prolog_flag(argv, [Me|_]), atomic_list_concat(['"', Me, '" "%1"'], OpenCommand), shell_register_file_type( Ext, 'prolog.type', 'Prolog Source', OpenCommand), shell_register_dde( 'prolog.type', consult, prolog, control, 'consult(''%1'')', Me), shell_register_dde( 'prolog.type', edit, prolog, control, 'edit(''%1'')', Me).
